Definitely needs the diagonal constraint, in exactly the way the author describes.

Nice puzzle! I actually solved it without using the diagonals. It should be possible!

@jplank Without the diagonal constraint, I can solve until I have only r3c2, r3c4, r4c2, r4c6, r6c4, and r6c6 left in a deadly pattern. I don't think it's possible to resolve this portion without the diagonals (although only one, not both are needed).
